Create healthy soil in your own backyard

by Diana Duff

If you are thinking you can’t grow food in your garden, think again. Many Kona residents don’t plant edible gardens believing they haven’t got good soil. Yes, we are soil-challenged here, but help is just a few months of easy recycling away.

We all have rocky soil. At lower elevations, soils are not only rocky but can also be dry and alkaline. At upper elevations, rocky soil is often wet, sometimes boggy, and acidic. No can grow? Wrong. If you think “no can,” try again. Since we are all on the sustainable path, composting presents a solution to two issues we face: recycling waste and building soil.

You can get started toward your gardening goal by getting some beds defined and laying in a passive compost pile that will give you a good soil base, alive with microorganisms. Use those pesky rocks to create borders for your beds, and then start piling garden waste into them. Cut material into small pieces for fast breakdown. For a base of decomposed waste in several months, mix dried leaves, leafy prunings, grass clippings, weeds (without seeds), broken up twigs and branches less than 1/2 inch diameter. If you live in a dry area, dampen the pile and cover it with a tarp or black plastic to maintain a dampness level comparable to a wrung out sponge. In wet areas, covering can help keep the pile from getting waterlogged, which can lead to smelly anaerobic decay. In any case, a balanced mix of organic inputs including green matter for nitrogen, brown (dry) matter for carbon, air and moisture speeds the process. After sitting for several months, you’ll have a base of decomposed organic matter. Mix in some of your rocky soil to improve aeration and you are ready to plant.
